I have the same problem. I'm running xp with sp3. Did chats 2 different times and phone help once. Tried everything imaginable. Then they wanted me to send log files, which I did. I think the software doesn't work with xp even though they advertise that it will. I hesitate to try it on windows 7 though. I don't need 2 machines screwed up at the same time.

I am running Win 8.1 and i have never gotten the new version to work that i bought and paid for and that Quicken has my money for. I had to reinstall my 2013 version and I am a very unhappy LOYAL Quicken customer.

Safemode is insufficient - you would need to use Safemode with Networking to have internet access necessary to register the program.

It may have nothing to do with firewall, but could be an aggressive anti-spam/anti-malware filter, cached browser pages, incorrect or stringent Internet Options settings, or even a filtering ISP that prevents certain levels of access (much the same as Parental Controls).

If you're attempting to use an existing Quicken.com user ID, try using the Create New to see if you get better results.

Chat Support would be insufficient for trying to resolve this, as many troubleshooting steps can require you to either reboot your computer or restart it in a different start up mode. Phone Support would be your best assistance.
